Description

FIELD

The present invention is related to a lighting apparatus, and more particularly related to a lighting apparatus with enhanced heat dissipation structure.

BACKGROUND

The time when the darkness is being lighten up by the light, human have noticed the need of lighting up this planet. Light has become one of the necessities we live with through the day and the night. During the darkness after sunset, there is no natural light, and human have been finding ways to light up the darkness with artificial light. From a torch, candles to the light we have nowadays, the use of light have been changed through decades and the development of lighting continues on.

Early human found the control of fire which is a turning point of the human history. Fire provides light to bright up the darkness that have allowed human activities to continue into the darker and colder hour of the hour after sunset. Fire gives human beings the first form of light and heat to cook food, make tools, have heat to live through cold winter and lighting to see in the dark.

Lighting is now not to be limited just for providing the light we need, but it is also for setting up the mood and atmosphere being created for an area. Proper lighting for an area needs a good combination of daylight conditions and artificial lights. There are many ways to improve lighting in a better cost and energy saving. LED lighting, a solid-state lamp that uses light-emitting diodes as the source of light, is a solution when it comes to energy-efficient lighting. LED lighting provides lower cost, energy saving and longer life span.

The major use of the light emitting diodes is for illumination. The light emitting diodes is recently used in light bulb, light strip or light tube for a longer lifetime and a lower energy consumption of the light. The light emitting diodes shows a new type of illumination which brings more convenience to our lives. Nowadays, light emitting diode light may be often seen in the market with various forms and affordable prices.

After the invention of LEDs, the neon indicator and incandescent lamps are gradually replaced. However, the cost of initial commercial LEDs was extremely high, making them rare to be applied for practical use. Also, LEDs only illuminated red light at early stage. The brightness of the light only could be used as indicator for it was too dark to illuminate an area. Unlike modern LEDs which are bound in transparent plastic cases, LEDs in early stage were packed in metal cases.

In 1878, Thomas Edison tried to make a usable light bulb after experimenting different materials. In November 1879, Edison filed a patent for an electric lamp with a carbon filament and keep testing to find the perfect filament for his light bulb. The highest melting point of any chemical element, tungsten, was known by Edison to be an excellent material for light bulb filaments, but the machinery needed to produce super-fine tungsten wire was not available in the late 19th century. Tungsten is still the primary material used in incandescent bulb filaments today.

Early candles were made in China in about 200 BC from whale fat and rice paper wick. They were made from other materials through time, like tallow, spermaceti, colza oil and beeswax until the discovery of paraffin wax which made production of candles cheap and affordable to everyone. Wick was also improved over time that made from paper, cotton, hemp and flax with different times and ways of burning. Although not a major light source now, candles are still here as decorative items and a light source in emergency situations. They are used for celebrations such as birthdays, religious rituals, for making atmosphere and as a decor.

Illumination has been improved throughout the times. Even now, the lighting device we used today are still being improved. From the illumination of the sun to the time when human can control fire for providing illumination which changed human history, we have been improving the lighting source for a better efficiency and sense. From the invention of candle, gas lamp, electric carbon arc lamp, kerosene lamp, light bulb, fluorescent lamp to LED lamp, the improvement of illumination shows the necessity of light in human lives.

There are various types of lighting apparatuses. When cost and light efficiency of LED have shown great effect compared with traditional lighting devices, people look for even better light output. It is important to recognize factors that can bring more satisfaction and light quality and flexibility.

When light devices are installed in various places, many different problems occur.

For example, there may be fire accident and the light devices need to be designed to prevent further damages on the fire accident.

It takes time and innovation to find out an effective solution while providing low cost and reliable design.

The driver module 602 is connected to a power wire 6111 via a wiring hole 611 disposed on the surrounding wall 604.

The light module 603 receives a driving current from the driver module 602.

The driving current is generated by the driver module 602 by rectifying an external power from the power wire 6111. For example, the power wire 6111 is connected to an indoor power of 11V/220V alternating current power source. The driver module 602 converts the received power to a direct current power by rectifying, filtering and other processing. The direct current power is supplied to the light module, e.g. to one or more LED modules of the light module to emit lights. In addition, the LED module may contain one type or multiple types of LED chips for mixing lights of required color, color temperature or intensity. The driver module may also receive a command from a wire or a wireless channel to adjust the output of the light module.

In some embodiments, the multiple rectangular plates are made of metal material or plastic material with high thermal conductive material. In some embodiments, the rectangular plates are made of material that can keep stable under high temperature, e.g. under a fire accident.

In some embodiments, the multiple rectangular plates are formed by bending a metal sheet. Specifically, the metal sheet is folded to form the surrounding wall. There are some structures like the wiring hole made by stamping on the metal sheet.

In some embodiments, the wiring hole has a hole cover with breakable pins connected to the surrounding wall before the power wire is installed. For example, FIG. 2 shows a wiring hole 110 with a hole cover with only a minimum connecting pin connected to the surrounding wall. Users may easily break the wiring hole during installation or assembly of the lighting apparatus.

In FIG. 11, the second clip end 6082 has a U-shape structure.

The U-shape structure has a first arm 6083, a second arm 6084 and an arm connector 6085.

The first arm 6083 and the second arm 6084 are connected by the arm connector 6085.

The first arm 6083 elastically engages the top cover 605 when the top cover 605 is closed by engaging the surrounding wall 604.

The second arm 6084 is used for being pressed to deform the second clip end 6082 for releasing the top cover 605. The elastic clip 100 illustrated in FIG. 4, FIG. 9 and FIG. 10 may be used as reference to implement such structure.

In FIG. 11, the light module 603 has a back cover 6031 for fixing to the surrounding wall 604.

In FIG. 4, the surrounding wall has multiple bottom ears 687 for fixing to the back cover of the light module.

In FIG. 4, the surrounding wall has multiple protruding pins 688 for inserting to the back cover to align the surrounding wall with the back cover. Specifically, there are some positioning holes for inserting the protruding pins 688 on the back cover of the light module.

In FIG. 11, the light module 603 has a thermal conductive path 6032 connected to the surrounding wall 604 for carrying heat of the light module 603 to the surrounding wall 604. For example, the thermal conductive path 6032 may be made of a metal strip or plate for effectively moves heat 6033 to the surrounding wall 604 via the thermal conductive path 6032.

In FIG. 3, a wire pressing plate 300 is disposed inside the surrounding wall for keeping the power wire in order.

In FIG. 11, a power terminal 6113 is fixed on the surrounding wall 604 for connecting to the power wire 6111 and the driver module 602. The power terminal 6113 may include a structure and a conductive strip so that the power wire 6111 is structurally and electrically connected to the power terminal 6113. The driver 602 is electrically connected to the power wire 6111 via the power terminal 6113.

In some embodiments, the surrounding wall has a guiding track 6115 for installing the driver module 602. For example, the driver module 602 has a driver plate to be inserted to the container space 607 via the guiding track 6115. When the drive module 602 reaches a predetermined position, the driver module 602 also engages the power terminal 6113. Such design makes the assembly of the lighting apparatus more easily, which may also reduce the manufacturing cost.

In some embodiments, there are multiple slots for selectively plugging multiple driver plates of the driver module. FIG. 11 shows one driver module 602 is inserted via the guiding track 6114. Other driver plates mounted with further functions may be placed with the same manner. For example, a basic driver plate may provide power conversion while another driver plate provides wireless connection. Other driver plate may provide sensor or IoT automatic functions.

In some embodiments, the multiple driver plates exchange a device signal for coordinating an operation among the multiple driver plates. For example, multiple driver plates are inserted to the driver box via guiding tracks as mentioned above. There are corresponding terminals like the power terminal to combine these driver plates so that the components on these driver plates may communicate. For example, a main driver plate may send an inquiry command to an interface like I2C that connects the multiple driver plates. When another driver plate receives the inquiry command, the driver plate replies with its type and capability to the main driver plate. With such signal exchanges, multiple driver plates may work together automatically and smartly.

In FIG. 12, the lighting apparatus may also include a conductive path module 685 attached to the surrounding wall for connecting the power terminal 688 and the driver module and for connecting the driver module to the light module 686.

In some embodiments, the surrounding wall has a first air passage 6041 and a second air passage 6042 disposed at two positions of the driver box 601.

The two positions of the driver box have different temperatures when the light module is turned on. For example, the first air passage 6041 is placed at a position with less temperature than the second air passage 6042. Therefore, the air would form a flow between the two

air passages

6041, 6042.

In some embodiments, the lighting apparatus may also include a fan 6043 for heat dissipation.

The fan 6043 receives power from the driver module 602 for moving air in the container space of the driver box 601.
